Sri Aurobindo describes the "power" of Saccidānanda (existence, consciousness, and bliss) that creates the world as the dynamic force responsible for the manifestation of the phenomenal universe.
1. Māyā: In this context, Māyā is the creative power of the Supreme Being, responsible for manifesting the diversity of the phenomenal world while maintaining unity in the essence of existence. Māyā creates the interplay of forces, consciousness, and delight mentioned in the passage.
2. Incorrect options:
- (B) Involution: Involution refers to the descent of the Supreme Consciousness into the material world but is not explicitly the "power" mentioned here.
- (C) Evolution: Evolution describes the ascent of consciousness from matter back to its divine source, which complements involution but is not the creative power described in the text.
- (D) Integral Yoga: Integral Yoga is Sri Aurobindo's practical philosophy for realizing divine consciousness but is not referred to as the "power" that creates the world.
Thus, the correct answer is (A) Māyā.
